Details for: Maroa
Ngangiho lava dome is one of at least 70 post-caldera lava domes erupted within the Maroa caldera, which formed sometime after about 230,000 years ago N of the Taupo caldera. The youngest of the post-caldera lava domes is Puketarata, which grew within a rhyolitic tuff ring about 14,000 years ago. The domes were erupted along a general SW-NE trend, parallel to the structural trend of the Taupo Volcanic Zone. No Holocene eruptions have occurred, but vigorous thermal activity continues.

Location: Karapiti (View Details at MaGa DB)
Description: Geothermal gas emissions from the Karapiti steaming ground area have been monitored since 1960 to assess the response of large manifestations to the development of the Wairakei reservoir.Heat flux measurements across the Karapiti area during the last few years have shown that practically all visible steam is discharged by fumaroles and steam vents (c. 41 kg/s, transferring c. 107 MW); a smaller proportion is discharged by diffuse emission (c. 27.5 kg transferring c. 69 MW) across the 0.35 km2 steaming ground area.
